Another WEB site had a long discussion on this and the Conclusion was it won't work with the Allison because it relies on that sensor output to run the transmission. If I was on my home computer, I could link the forum, but I am on the road. This apparently works on the over the road trucks with the manual and semi-automatic transmissions only.
